PACKING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 592,750, dated October 26, 1897.

I Application filed December 1, 1888. Serial No. 292,412. (No model.)

To all whom it may concern:

Be it known that 1, JOHN H. DAY, a citizen of the United States, and a resident of the city.

of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Packing-Machines, of which the following-is aspecification.

The several features of my invention and the advantages arising from their use, conjointly or otherwise, will be apparent from the following description.

In the accompanying drawings, forming part of this specification, Figure 1 is a front elevation of the machine. Fig. 2 is a side elevation of the same. Fig. 3 is a detail view illustrating the position of the parts when the receptacle or receptacles have been filled and the receiving-platform 'is held down. Fig. 4 illustrates the revolving disk for carrying a number of separate packages. Fig. 5 is a front view of the lever for throwing the clutch and of the lower portion of avertically-moving stem, showing its mode of throwing the clutch-lever, the view being taken from behind the lever F, hereinafter mentioned, and looking from right to left in Fig. 2. Fig. 6 is a View of the delivery-tube provided with outlying flange and felt secured thereto.

A suitable supporting-frame has at its upper part the hopper A, which is preferably provided with an opening c or an equivalent series of smaller openings covered by a transparent substance to show the state of the contents of the hopper. The hopper A terminates in the spout a. I

The shaft B (shown in dotted lines in Fig. 2) passes vertically through the axis of the hopper and terminates in the auger b, which occupies the spout a. vided with suitable stirrers located in the hopper. One kind of these stirrers is shown in dotted lines.

The shaft B is operated by the shaft A through the agency of the beveled gears A A The shaft A carries the clutch a for throwing the driving-pulley a in and out of gear. As shown in Fig. 1, the clutch is out of gear. The spout a of the hopper A is surrounded by the sliding collar 0, which is pressed downward by the spiral spring 0.

The shaft B is pro-.

Here the felt is screwed or bolted at a to'the under side of the flange, the outer peripheral edge of the felt being free to yield and pass within the top portion of the receptacle to be filled, and at the same time its elasticity causes it to press closely against the inner wall or surface of the receptacle and prevent the egress of the substance to be packed during the operation of filling the receptacle. The felt C on the lower side of the collar 0 presses on the top edge of the can or package and still further revents the escape therefrom of any dust or other parts of the material to be packed. The presence of these layers of felt are very desirable in packing those materials which are very liable to produce dust-such as baking-powder and fine dry paints or drugs, &c. In packing articles less finely comminuted either the collar 'or the felt on the tube, or both, can be omitted.

The platform D is mounted on the stem 01 immediately under the hopper-spout. The stem 01 passes through the table T or other suitable support of the framework and iron plate T, and has attached to its lower end the belt E. The belt E passes over the pulley E and bears at its other end the weights W. The lever F is fulcrumed in the iron plate T or equivalent support and is provided with the handle f and below with the lug f.

moved and set vertically at different points relatively to the bearing-piecef A convenient means for this purpose consists of thumbscrew f which passes through the slot f in The bearing-piece F is adjustably attached to the lever F, so that it can be piece F, or a suitable hand-wheel and screw 5 may be used in lieu thereof. The slot f permits a vertical adjustment of the piece F. Below the lever F the piece F is provided with the shoulder f against which the tappet d on the stem d strikes as it descends.

IOO

A convenient mode of forming this shoulder consists in bending the piece F toward the stem (Z.

The spring G is preferably provided and attached, as shown, to cause the lever F to continually press in the proper direction.

The lever II is conveniently fulcrumed to the frame or to a cross-piece", as shown. It projects alongside the stem (1 and is provided with the lateral tappet 7L2, which rests on the lug f when the machine is in motion. The rod h extends upward from the lever II and connects with the bent lever h, that operates the clutch a Instead of the platform D always carrying a single package I sometimes provide the package-holder L of a disk or other desired form. The holder L is rotatable and suitably supported. In the pres ent illustrative instance itis centered upon a pin j, which latter is centered in a sector J or equivalent support, attached to the top of the stem (1. It is provided with a number of spaces Z to hold empty packages, and in its rim the notches Z, corresponding in number to the spaces 1, are cut. The spring-pawl M is attached to the sector J and bears against the edge of the disk L, its lug m slipping into the notches l, in this way holding the disk L in position.

The machine is intended for packing granular or powdered substances.

The mode of action of the device is follows: The substance to be packed is placed in the hopper. An empty package is placed upon the platform D or a series of packages on the disk L and the stem (1 raised by the weight IV to the position shown in Fig. 2. In this position the package P surrounds the spout a with its top bearing against the collar 0. As the auger fills the package the stem dis forced downward, raising the weight 7. This weight \V is constructed of a number of removable rings or disks, as shown in Figs. 2 and 3 of the drawings, which may be removed from or added to said weight to diminish or increase it, and thereby secure the desired density of packing. The collar 0 descends with the package P, being forced down by the spring 0, and in this way keeps the top of the package covered and prevents the escape of its contents. lVhen the package is filled, the tappet (1 reaches the shoulder f which has been adjusted with this object in view,and, moving the lever F backwardly, draws the lug f from under the tappet 7L2 and permits the lever II to drop. The dropping of the lever II throws the clutch a out of gear and stops the machine.

Vhen the filled package is removed and another put in its place either by being placed on the platform D or by revolving the disk L, the weight \V is permitted to raise the platform D into the position shown in Fig. 2. As the stem (Z rises the tappet d raises the lever II into the position shown in Fig. 2 and in dotted lines in Fig. 1, and the clutch being thrown in gear by this means the machine starts up.

hen it is desired to stop the machine, the stem (1 is drawn down either by hand or by the aid of the lever and connecting-rod shown in dotted lines in Fig. 2 until the tappet d catches under the bottom of the piece F, as shown in Fig. 3.

To start the machine again, it only becomes necessary to move the handle f slightly inward, which releases the tappet d from under the piece F.

\Vhen desired, a foot-lever can be connected to the strap E, preferably beneath the weight \V, and employed to enable the operator by the pressure of his foot to raise the package up to the tube a, thereby enabling his hands to be otherwise employed.

The movable ring provided with felt and the presence of the felt at the bottom of the tube is designed especially for use in packing such substances as are very dusty, and the use of the tube and felt is to confine the dust from escaping into the room. XVhere the substance is not specially dusty, the ring with felt or the felt on the bottom of the tube, or both, may be dispensed with.

Vhile the various features of my invention are preferably employed together, one or more of them may be used Without the remainder, and in so far as applicable one or more of said features may be used in connection with packing devices or machines other than the one hereinparticularly described.

\Vhat I claim as new, and desire to secure by Letters Patent, is-
